So far we were not using the FIT image format to its full potential: The SPL FIT loader was just loading the first image from the /images node plus one of the listed DTBs. Now with the refactored loader code it's easy to load an arbitrary number of images in addition to the two mentioned above. As described in the FIT image source file format description, iterate over all images listed at the "loadables" property in the configuration node and load every image at its desired location. This allows to load any kind of images: - firmware images to execute before U-Boot proper (for instance ARM Trusted Firmware (ATF)) - firmware images for management processors (SCP, arisc, ...) - firmware images for devices like WiFi controllers - bit files for FPGAs - additional configuration data - kernels and/or ramdisks The actual usage of this feature would be platform and/or board specific. Also update the FIT documentation to mention the new SPL feature and provide an example .its file to demonstrate its features.
